Stigy, consider an out of area location. We got married in NC which was SO much cheaper than anywhere in the DC metro area. This was the site:
The Fields at Blackberry Cove
We had an outstanding time and the site manager was AMAZING in helping us with local vendors and the challenges that the day presented (:cough: no electricity :cough

This was our caterer:
Saffron Fine Foods
Food was amazing and very well priced considering how much local ingredients they use (all the meats/veggies).
